How To Weld Vinyl Sheets

If acrylic sheeting is being welded for box corner joints apply solvent on the inside edge of the acrylic sheeting.

How to weld vinyl sheets.

When heat welding inside and outside corners use two small pieces of blue painter s tape on the floor to prevent scorching or burning when starting or stopping the vinyl weld. Apply a uniform bead 1 8 to 1 4 wide centered at the seam. Remember heat welded seams are primarily used in aseptic or clean areas to prevent joints where bacteria and pathogens can collect. Heat welding vinyl floor with heat gun hot air gun.

The bead of sealer must flow back together around the needle after it has been applied to the seam. This helps achieve a strong weld at the starting and stopping point without damaging the floor and the tape comes off with no residue. Make sure that the width of the ribbon that s cut from the edge of each sheet is the same. Heat weld seams that are splitting or pulling out are often referred to as cold spots which means the vinyl welding rod and flooring did not get hot enough to achieve a strong monolithic bond.

The general procedure used to manually groove and heat weld a seam in commercial vinyl is as follows. The temperature setting for sheet vinyl is 650 850 f 340 450 c. Leave the tape approximately 1 8 from the starting and stopping point of the groove and weld right onto the tape. In this instructional video you will learn the basics.

Make sure to consider the power supply as well as the length and size of the extension cord when setting the proper temperature. Apply cement solvent on both sides of sheeting if you re applying to flat joints. As the needle is drawn along the seam the sheets separate slightly which will allow the fluid to flow between them. Use clamps or masking tape to hold acrylic sheeting in place while applying solvent.

Groove out the seam to two thirds of the depth of the material with a hand groover or turbo groover.
